Chinese Breakfast Crepe - Jian Bing?

I think that's what they're called, based on what my googling. I just got back from a short vacation in Beijing, and we bought these for breakfast from a streetcorner stand and I fell in love. It's a savory crepe that's filled with scallions, sesame seeds, an egg, two different sauces (maybe something like hoisin and a bean paste) and a hunk of puffy fried dough, then folded and stuffed into a baggie to eat by hand on the go. I wish I could've had them for breakfast every morning! I was just about to post to see if anybody knew a place to get these in NY, when I noticed there's already a thread. But there's only one suggestion (a cart near the 6 train entrance at Canal and Lafayette) with no report back of whether it was successful. I'd be so excited to find a place to get them in NY, I'd even get up early for them!

Any ideas? In Manhattan or other boroughs?
Thanks!
